CwSkimmer 6300

I am running at Flex 6500 and a Flex 6300 different QTH and the settings are exactly the same and should work as it sits.

What I am seeing is that when I start SDR Bridge and skimmer the 6300 goes instantly into transmit. The only way to stop it is by shutting the radio down, The MOX button is lit and hitting stops the transmit for about as long as you hold the button down. It then returns to transmitting.
